Abstract

This paper discusses the temperature related hydrogen input and output characteristics of a metal hydride tank to be used for a hybrid electrical wheelchair with photovoltaic cells and fuel cells. The temperature of a metal hydride tank increases when it is filled with hydrogen and decreases as the hydrogen is ejected. A metal hydride tank is unable to eject hydrogen at low temperatures, therefore it is very important to understand the relations between tank temperature and hydrogen admission and ejection characteristics. The experimental results of these processes are evaluated, and an improved scheme to increase the distance the hybrid wheelchair will travel is proposed.
